I would like to point you to the
Mini symposium at the 14th International Conference on Fracture Rhodes, June 18-23 2017
on Atomistic and Mesoscale Aspects of Fracture and Fatigue
Chair: Prof. Peter Gumbsch, Karlsruhe Institute of Technology & Fraunhofer IWM, Germany
Co-chair: Dr Gianpietro Moras, Fraunhofer IWM, Germany
Elastomers and gels can often deform multiple times their original length. The stretchability is insensitive to small cuts in the samples, but reduces markedly when the cuts are large. This work shows that this transition occurs when the depth of cut exceeds a material-specific length, defined by the ratio of the fracture energy measured in the large-cut limit and the work to rupture measured in the small-cut limit. This conclusion generalizes a result in the fracture mechanics of hard materials.
Hi I have long been looking for a clear way of defining stress intensity factors. Apart from the usual bookinsh definitions such as "strength of singularity" "state of stress". Of course I could convince myself by relating SIF with Strain Energy Release Rate (G) as 'G' has a more convincing physical meaning explained through the creating of new surfaces. This kind of gives the feeling that 'K' is a derived quantity in the field of fracture mechanics.
So is there a better way of explaining SIF without having to go through 'G'.
Thanks and Regards
Dear Colleague,
I kindly inform you that, in the framework of the 14th International
Conference on Fracture (ICF14), to be held in Rhodes, Greece, June 18-23,
2017, we are organizing a mini-symposium on "Fracture and contact in
multiphysics problems: from energy to biological applications".
If you are interested, please submit your two-page abstract through the
ICF14 website (www.icf14.org) by October 31, 2016, selecting our
mini-symposium.

Postdoctoral Research Fellow position in hydro-fracturing (fracking) is
available immediately at Masdar Institute of Science and Technology in Abu
Dhabi in United Arab Emirates. Masdar Institute is established in collaboration
with Massachusetts Institute of Technology. The research project focuses on
using advanced computational fracture and damage mechanics for simulating
hydro-fracturing of rocks in hydrocarbon fields. The candidate is expected to
have a PhD in the field of geomechanics, or civil engineering with solid
I'm attempting to compile a local compliance matrix using Castigliano's theorem as described here. I'm having trouble with it and attempted to do a simple example by hand and picked the double cantilever beam specimen and analyzed it with Euler-Bernoulli beam theory (attached). Despite my best efforts, I can't reproduce the correct answer using the theorem as is but only if I modify the limits of integration.
